a number cube is rolled 360 times and the results are recorded: 54 ones, 60 twos, 66 threes, 71 fours, 35 fives, 74 sixes. what is the experimental probability of rolling a two or a three?
0.15
0.35
0.1
0.65
The experimental probability of rolling a two or a three is the sum of the number of times a two or a three was rolled divided by the total number of times the cube was rolled:
experimental probability = (60 + 66) / 360 = 0.35
Therefore, the answer is 0.35.
